In accordance with the object of different types of AC motor, speed of modern communication systems can be divided into induction motor and synchronous motor drives. Here are introduced the system of induction motor.1.1 induction motor speed control system of the basic types of By the induction motor working principle, we can see that from the stator into electromagnetic power can be divided into two parts: =(1-s)is the effective power load drag; another part of the deterioration of quality of power=sand s is proportional to slip . How to deal with deterioration of quality of power is consumed or feedback to the grid, and measurable system of induction motor efficiency. Therefore by poor power to the different treatment of modern induction motor can be divided into three types of speed control system. (1) power consumption and deterioration of quality-based speed control system Poor power switch are converted to the form of calories consumed. Thyristor Surge speed fall into this category. In the induction motor speed control system, the minimum efficiency of such systems is to increase power consumption and deterioration of quality in exchange for the cost of lower speed. (2) to poor power feedback-based speed control system To deteriorate to a small portion of power consumed by the majority of variable flow control devices to the power grid feedback. Lower speed, more power to repay. Wound cascade induction motor speed and doubly-fed fall into this category. (3) to deteriorate to the same power-based speed control system And deterioration of quality of power in the rotor part of the consumption of copper loss is inevitable, but in such systems, both high and low speed, power consumption and deterioration of quality is essentially the same, therefore high efficiency. VVVF fall into this category. AC Drive System is currently in, the application of a maximum of VVVF, the most extensive, can constitute a high dynamic performance of AC Drive System to replace the DC drive.1.2 AC speed control system of modern development trends and developmentsLooking at the speed of development of the exchange process and the status quo, we can see that speed of modern communication technology trends and future development trends. (1) to replace the DC drive system for the purpose of exchange of high-performance speed control system for further research and development;(2) the new power converter topology of the research and development; (3) PWM mode of improvement and optimization; (4) medium voltage variable frequency device research and technology development. 1.2.1 Control concepts and control technology research and development Application of more than a decade show that the theory of vector control and other application of control theory has yet to be governor with the development of the exchange continued to be refined, so as to further enhance the exchange of the control performance speed control system. Various control structures are based on mathematical model of the object, therefore, in order to establish a reasonable exchange of speed control system applicable to the control structure, need to exchange the motor mathematical model of the nature, characteristics and the inherent law of in-depth study and discussion . AC Drive System in particular, the synthesis and calibration methods of the theory and engineering design of future AC Drive System is an important research topic. By the rotor flux-oriented induction motor vector control system to achieve the excitation current and torque current full decoupling, the mathematical model and the DC torque motor torque exactly the same model. However, the estimated rotor parameters and parameter changes do not affect the accuracy of directional coordinates of the offset caused by a problem which has not really solve the problem at home and abroad, so the rotor parameter identification and parameter changes for the future of the adaptive control of the critical study of vector control issues. In recent years, do not rely on the electrical model of fuzzy self-optimizing control, such as artificial neural network intelligent control method has been introduced to the AC Drive system, as a governor to control the exchange theory, control technology research and development of new directions. Direct Torque Control technology practice in the application of continuous improvement and upgrading of the main direction of its research to address low speed motor flux parameters on the impact of trajectory to further improve the control of low speed performance, t
